Information processing apparatus and correction method

A correction method comprising:

• receiving signals, which are transmitted from a fixed station, including identification information for identifying the fixed station;
• measuring receive signal strength indications of the received signals;
• acquiring position information indicating positions at which the receive signal strength indications are measured, the receive signal strength indications, and the identification information in association with each other;
• and
• calculating correction information including a transmission antenna gain in a specific direction from the fixed station identified by the identification information and an attenuation rate in a propagation path, the correction information being obtained from the receive signal strength indication measured at a first distance in the specific direction from the fixed station identified by the identification information and the receive signal strength indication measured at a second distance in the specific direction that is different from the first distance, among the measured receive signal strength indications.

A non-transitory computer-readable recording medium storing a program for causing a computer to execute a method comprising:

• receiving signals, which are transmitted from a fixed station, including identification information for identifying the fixed station;
• measuring receive signal strength indications of the received signals;
• acquiring position information indicating positions at which the receive signal strength indications are measured, the receive signal strength indications, and the identification information in association with each other;
• and
• calculating correction information including a transmission antenna gain in a specific direction from the fixed station identified by the identification information and an attenuation rate in a propagation path, the correction information being obtained from the receive signal strength indication measured at a first distance in the specific direction from the fixed station identified by the identification information and the receive signal strength indication measured at a second distance in the specific direction that is different from the first distance, among the measured receive signal strength indications.
